Question about Dell Latitude C400 Notebook
I don't know how old your system is but the battery packs have lifetimes that seem to vary from about 6 months to a couple of years.
I'm curious as to how you have established that the battery is getting 'full charge?'
The three keyboard LEDs are the start of the 'power-on self-check' and the fact that they go out again can mean that they are finished with the keyboard test and that the initialization is proceeding or that the battery voltage has collapsed.
If you don't own a multimeter (you should-they are cheap) I don't know how you know whether the battery pack is charged or not.
Battery packs can also fail without dying of old age; there is a thermal fuse in all of them that will melt open if the temperature surpasses a safe point (fairly low) and these Chinese parts are terribly unreliable and may fail just for fun. When this happens, they will not charge and in some, they won't produce any voltage at the pack's contacts either.
